这是我用来从 Apple 的 UK Top 10 rss 提要中获取 xml 数据的代码：

xml = Net::HTTP.get_response(URI.parse('http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/ws/RSS/topsongs/limit=10/xml')).body

辛纳屈回归Errno::ECONNRESET at / - Connection reset by peer。我用于此的 RSS url 是从 Apple RSS 生成器生成的。其他国家/地区的 RSS 提要会出现此错误，但此处的默认提要（美国）不会出现此错误。回溯如下：

/usr/lib/ruby/1.9.1/net/protocol.rb in read_nonblock
        @rbuf << @io.read_nonblock(BUFSIZE)
/usr/lib/ruby/1.9.1/net/protocol.rb in rbuf_fill

        httpv, code, msg = read_status_line(sock)

自己解决了这个问题。原来我使用了错误的 Net:HTTP 命令。本来应该Net::HTTP.get('itunes.apple.com','/gb/rss/topsongs/limit=10/xml')
